Abstract: A soft-switching auxiliary circuit is provided, which may be applicable to a converter including a first main switch and a second main switch. The soft-switching auxiliary circuit may include a first auxiliary switch, a second auxiliary switch, a first energy adjustment module and a second energy adjustment module. By means of the first auxiliary switch and a second auxiliary switch, the first energy adjustment module and the second energy adjustment may properly store and adjust the energy of the converter; therefore, both the first main switch and the second main switch of the converter can achieve soft-switching.

Abstract: A diagnosis circuit comprises: a logic circuit, wherein the logic circuit comprises a set having a gate voltage terminal of an arm of a phase logical OR a dead time voltage terminal, and the set logical XOR a drain-source voltage terminal of another arm of the phase; a filter circuit coupled to the logic circuit, wherein the filter circuit is configured to filter transient noises; a comparison circuit coupled to the filter circuit, wherein the comparison circuit is configured to determine whether a phase current of a phase current terminal of the phase is greater than zero; and a latch coupled to the comparison circuit, wherein the latch is configured to store diagnosis signals temporarily.
